The 1 register of CVR (Comparator voltage reference), from 0xBF809800, with their reset value and every field. The PIC32MX550F256H has 675 registers in 55 peripherals, one page each.
Most PIC32 SFRs have three more registers right after them: CLR at +4, SET at +8 and INV at +C (T1CONCLR, T1CONSET, T1CONINV), which clear, set or flip just the bits written as 1, in one write.

Comparator Voltage Reference On bit
0 Module is disabled and does not consume current. Clearing this bit does not affect the other bits in the register.
1 Module is enabled. Setting this bit does not affect other bits in the register.
CVROE

CVrefout Enable bit
0 Voltage level is disconnected from CVrefout pin
1 Voltage level is output on CVrefout pin
CVRR

CVref Range Selection bit
0 0.25 CVrsrc to 0.75 CVrsrc with CVrsrc/32 step size
1 0 to 0.67 CVrsrc with CVrsrc/24 step size
